Chapter 199

To some extent, perpetual motion machine is also the long cherished wish of mages for many years. However, just like the most powerful legendary mage, it will fall one day. No machine or magic in the world can operate continuously without external power supply.

"Perpetual motion machine..."

this is a typical routine of civil science, which Leiner thought.

"Can we go and have a look?"

He asked, Lena hasn't seen how the world designs perpetual motion machines. He doesn't know if it will be different in the face of the power of magic.

"I think so. I don't think the conference room is closed."

Igor has been sitting in a chair, eyes on the desktop of a paper, it seems lack of interest.

"Then I'll see."

Lena didn't force Igor, so he got out of the office and went into the conference room next door.

As soon as he went in, Lena saw director Percival and Roger. They were sitting on the sofa with a paper in each hand. Opposite them, a young man was looking at them with high spirits. He didn't notice until Lena came near.

"Why, what is it?"

The young man wore elegant robes and embroidered a gold border on the cuff according to the regulations of the association to show his status as a wizard.

He looked up and down at Lena, noticed the identity of Lena, and subconsciously thought that he was a master in charge of miscellaneous work.

"Lena, why are you here..."

director pasiwar raised his head and looked at Lena, then he was helpless.

"Come on, you sit by and watch."

He pointed to a row of chairs against the wall of the conference room. Since Lena had come, it was not convenient to drive him away. Pasival only hoped that Lena would not make trouble.

"My father often talked about you, Lord Orson. He said that you are a promising mage and may even be promoted to a higher level in the future."

The young man didn't notice the whispers of pasiwar and Lena. He said quietly while the two judges were examining the paper.

"I'm flattered, Mr. duravin. I'm just doing my duty."

Pasiwar replied that he had put down his paper and seemed to have a good idea.

"How about the" eternal pendulum "I designed? Is it very innovative? It solves the problem that has plagued mages for thousands of years with such a simple method. To be honest, I didn't expect that I was so smart."

The young man asked again, with an indescribable pride in his words.

"Ha ha, I don't think people like Lena Ian gray can come up with such a brilliant idea. I don't know if he, who is known as the most promising advanced mage in 50 years, will have a cognitive collapse and explode on the spot when he sees my thesis."

He had no words to hide. It was obvious that his father, who did not know where he came from, might not have taught him to keep a low profile.

When he heard Mr. duraven's words, pasival had no choice but to smile. Instead of explaining more, he waited for Roger to finish the review.

About five minutes later, Roger with one-sided glasses put down his paper.

"Roger, let me start with your opinion."

In dulaven's expectant eyes, pasiwar asked Roger to judge first.

Roger picked up the paper again, looked at it, and said.

"There are some innovations in the design, well, there are few examples in the past..."

"right, I said, this is unique design, you are witnessing history!"

Duraven said eagerly, his voice full of excitement.

"Er, but..."

Roger took a pause, looked at Percival, and then continued.

"But this design, I don't think, can achieve the ability of continuous and permanent operation without any external energy supply. This is not a perpetual motion machine."

Roger's words widened duraven's eyes and made him look unbelievable.

He was stunned for a long time, then he said, his expression was a little cloudy.

"Sir, I suggest you reread my paper. I believe you will have different opinions."

"Actually."

Chief pasiwar said at this time.

"I also think that there are big flaws in the design, which is far from perpetual motion."

Lena was surprised by the attitude of these two people. He thought that according to Igor, they were all muddlers here. Maybe director pasiwal would pass each other's papers against his will because of the power of duraven's father, but he didn't expect that these two people still maintained the basic quality of seeking truth from facts.

"You can't understand the secret at all!"

Duraven's original image of politeness collapsed. He knocked on the table and argued discontentedly.

"Come and see."Director pasiwar suddenly turned his head and handed dulaven's paper to Lena.

"Well, OK."

Lena didn't know which one he was singing. Clearly in the morning, director pasiwar asked him to do his job well and stop meddling.

He took the paper and soon saw the design of the so-called perpetual motion machine.

It's a roulette with twelve sticks of equal length on it. One end of the stick is a small ball. When the roulette rotates, the small ball on one side will be far away from the axis because of the centripetal force, while the other side will be close to the axis. It seems that it can keep running forever relying on the transformation and inertia of the centripetal force.

"How can a one link mage understand the subtlety of my design, Mr. pasiwar? Listen to me..."

"of course, it can't be a perpetual motion machine."

Lena interrupted, and without waiting for dulaven to retort, he continued.

"It seems that it can run continuously, but in fact, the number of small balls on the left and right sides of the rotating shaft is not the same. If we establish a mathematical model, we can get these equations..."

he soon began to write on the blackboard in the conference room, established a series of equations, and finally got the same equations on both sides by substituting and eliminating answer.

"In other words, when this condition is reached, the whole machine will stop running because of force balance, which proves that this design is not a perpetual motion machine, it is a simple mathematical calculation, and the required mathematical level is not even higher than the second ring. I don't know why this Mr. duraven didn't calculate by himself first."

Lena put down his chalk, and he saw that director pasiwar opened his eyes slightly. This series of calculations obviously exceeded his expectation.

On the other side, dulawen is red. Obviously, this way of using mathematical means to completely negate his thesis makes dulawen feel greatly humiliated. His hands tremble slightly, and he is about to explode.

"Who are you to question me like that?"

He asked in a deep voice, gnashing his teeth.

"Lena Ian gray, if you remember correctly, you're going to blow my head off?"

Putting down the chalk, Lena patted the chalk on her hands.
